If you want to add an inline mic and volume control to headphones you already own, choose Asobilor USB-C Audio Cable; if you need a complete wired in-ear headset with a mic and mute built in, choose KASOTT SoundMaster Pro V1.
• Asobilor USB-C Audio Cable — biggest strength: it turns existing 3.5mm headphones into a USB-C headset with an inline mic and click controls, no adapter needed. Biggest trade-off: it's a cable, so the sound you get is the sound your own headphones already deliver.
• KASOTT SoundMaster Pro V1 — biggest strength: a complete in-ear headset with 10mm dynamic drivers, a 45° ergonomic fit, three eartip sizes, and an in-line remote with mute. Biggest trade-off: it terminates in a 3.5mm jack, so USB-C-only phones and tablets need their own adapter.
• Who the Asobilor is for: anyone with Beats or similar 3.5mm headphones who wants calls and volume control on a modern USB-C device.
• Who the KASOTT is for: gamers and call-takers who want an all-in-one wired headset for a 3.5mm port on a console, controller, or PC.
The Asobilor is a 4.4ft USB-C to 3.5mm audio cable, and the pitch is narrow on purpose. You plug your existing headphones into the 3.5mm end and the USB-C end into your phone, tablet, laptop, or PC. The brand lists compatibility with Beats Solo2/Solo3/Solo Pro, Studio2/Studio3/Studio Pro, Mixr, and Executive headphones, and with iPhone 17/16/15, USB-C iPad, and computers. No adapter in between.
What you're really buying is the inline module. There's a built-in microphone plus click buttons: one press of the red button pauses or resumes, two presses skip forward, three presses go back, and the black buttons handle volume up and down. That's the whole reason to own this cable. If your headphones sound good but you've been stuck holding your phone to take a call, this is the fix. The 4.4ft length is comfortable at a desk and still fine walking around.
Who should skip it: anyone who wants an actual pair of earphones. This is a cable — if you don't already own 3.5mm headphones you like, there's nothing here for you. And if your device still uses a headphone jack, you don't need a USB-C audio cable at all.
KASOTT SoundMaster Pro V1: Who It's For
The KASOTT SoundMaster Pro V1 is a different kind of product entirely: a wired in-ear gaming headset. It uses 10mm dynamic drivers, and the brand's own framing is about gaming audio — faint explosions, character voices, gunshots, footsteps rendered with a sense of direction and placement. That positional feel is the point of a set like this, and 10mm dynamic drivers are a reasonable foundation for it. The brand also says it works for music and calls.
The fit is the other half of the story. The earbuds have a 45° inclined design and ship with three eartip sizes — small, medium, and large. The stated goal is a secure fit that won't fall out, with flexible material to reduce the soreness that comes from long sessions, and without the weight and heat of over-ear gaming headsets. As an in-ear design, the brand credits it with good sound isolation and comfort for home, out-and-about, and travel use. The housings are aluminum in a flaming red finish.
On the remote there are three quick-action buttons for volume and mute, and the brand says it works with compatible iOS and Android devices via the in-line remote. Connectivity is a 3.5mm jack, wired, and the listed compatibility covers Xbox Series, Xbox One, PS5, PS4, Switch, and PC with 3.5mm aux. It's sold as one unit with a two-year warranty, aimed at adults.
Who should skip it: anyone whose phone or tablet has no headphone jack and who doesn't want to carry an adapter. And if you already own a pair of headphones you love, you're paying for a whole headset you don't need.
• Best for reusing headphones you already own → Asobilor USB-C Audio Cable. It converts a 3.5mm pair into a USB-C headset with a mic.
• Best for consoles and controllers → KASOTT SoundMaster Pro V1. It's built for Xbox Series, Xbox One, PS5, PS4, Switch, and PC over 3.5mm.
• Best for USB-C-only phones and tablets → Asobilor. It connects straight to iPhone 17/16/15 and USB-C iPad with no adapter.
• Best for a complete headset out of the box → KASOTT. Earbuds, mic, mute, and three eartip sizes are all included.
• Best for long gaming sessions → KASOTT. The 45° ergonomic shape and three eartip sizes are designed around extended wear.
• Best for calls on a computer → either. The Asobilor gives you a mic on your existing headphones; the KASOTT gives you a mic on a headset with a mute button.
• Best for positional in-game audio → KASOTT. The 10mm dynamic drivers are tuned for footsteps and directional cues.
• Best for durability-minded buyers → Asobilor. Strain-relief connectors and a bend-tested, tangle-resistant jacket are explicitly part of the design.
In my opinion, the right pick comes down to one question: do you already own headphones you like? If yes, I'd buy the Asobilor USB-C Audio Cable. It's the cheaper way to get an inline mic and volume control onto gear you already trust, and it solves the USB-C problem directly. If you don't own a good pair — or you play on a console — I'd buy the KASOTT SoundMaster Pro V1, because it hands you a complete headset with mute, a proper fit system, and drivers tuned for games. For pure wired-headphones-with-inline-mic duty on a modern USB-C device, the Asobilor is the one I'd reach for. Check the current price on Amazon before you commit, since that's the one thing that can tip a close call.
what is an inline mic on headphones
An inline mic is a small microphone built into the cable's remote module rather than into the earcup. On the Asobilor cable, that module also carries volume and playback buttons. On the KASOTT SoundMaster Pro V1, the in-line remote adds mute and volume control.
how to use wired headphones with mic on pc
Plug the cable or headset into your computer's audio connection and select it as the input and output device in your sound settings. With the Asobilor, connect your headphones to the 3.5mm end and the USB-C end to the PC. With the KASOTT, use the 3.5mm jack on a compatible PC or controller.
It depends on the port. The Asobilor goes USB-C to 3.5mm, so it suits USB-C devices like iPhone 15/16/17, USB-C iPad, laptops, and PCs. The KASOTT ends in a 3.5mm jack, so USB-C-only devices would need their own adapter.
In my opinion the KASOTT SoundMaster Pro V1, because its 10mm dynamic drivers and positional tuning are aimed at in-game audio and it lists console compatibility. The Asobilor is the better fit if you just want your own headphones to work with mic and volume on a USB-C device.
